A. HENRY LowELL, Aor MANCHESTER, NEw 'HAMPSHIRE .HOSE-COUPLING.

Specification of Letters Patent No. 24,811, dated July 19, 1859.m

To all whom it may concern:

Be it known that I, A. HENRY LOWELL, of Manchester, in the county ofHillsboro and State of New Hampshire, have invented certain new anduseful Improvements in Hose-Couplings; and I do hereby declare that thesame are described and represented in the following specification anddrawings.

To enable others skilled in the art to make and use my improvements Iwill proceed to describe their construction and opertion referring tothe drawings in which the same letters indicate like parts in each offigures.

Figures l, and 2 are side elevations of my improved coupling separated.Figs. 3 and t are end elevations of the same. Fig. 5, is a sideelevation of one part showing the cap or female screw in section. Fig.6, is a section of the other part cut through the center longitudinally.

The nature of my invention consists in the arrangement of certainlocking devices which will be hereafter described, in combination with ascreen and cap arranged in connection with said locking devices.

In the accompanying drawings A, is a short tube with a flange or collarB, around the outside, as shown in section Fig. 5. That portion of thetube A, to the right of the collar B may have a screw thread on it tofacilitate its connect-ion and fastening to the end of the hose. 'Ihatportion of the tube to the right of the collar B, has two pins C, C,fastened in it by which it is locked to the tube D, Fig. 2, which tubeD, is made in the form shown in the drawings with a flange or collar E,on the outside provided with pins, E, F, to which wrenches may beapplied to turn the coupling in connecting' or disconnecting. The frontend of the tube D, is made to slip onto the end Gr, of the tube A, andhas two grooves H, H, on the inside to receive the pins C, C, whichgrooves H, H, terminate in a circular groove I, as shown in F ig. 6, sothat when the end of the tube A is put into the tube D, the pins C, C,pass through the grooves H, H, into the circular groove I, as the partsA, and D, are pushed together, and one turned while the other is held soas to carry the pins C, C, from the grooves H, H, int-o the groove I,and hold the two parts of the coupling together until the pins areturned opposite the grooves H, H, again in order to separate it.

In order to hold this coupling together and allow one part to be turnedin the other to take the twist out of the hose, and not allow the pinsC, C, to slip out of the circular groove I, I make a male screw on theend J, of the tube D, and apply a short tube K, to the outside of thetube A, as shown in section Fig. 5, and fit it to turn freely againstthe rear side of the collar B, while the front end of the tube K,extends over the end G, and is provided with a female screw fitted tothe male screw, on the end J, of the tube D. The tube K, is so arrangedthat it may be slipped back on the tube A, when the end G is insertedinto the tube D, and locked `by turning it so as to carry the pins intothe circular groove to hold A, and D, together, while the tube K, isscrewed onto the erd of D, by wrenches applied to the pins L, L, andafter the tube K, is screwed onto D, so as to prevent the pins C, C,from slipping out of the circular groove, the tubes A, and D, may beturned in opposite directions to take any twist out of the hose that mayhave been left in it when the parts A and D, were locked together.

The bore of the rear end of the tube D, is smaller than the front end,so that a shoulder is formed to which a leather ring or packing may beapplied if desired. And there is a screw thread on the outside of therear end of the tube D, to facilitate the fastening of the hose appliedto it.

Rings of leather or other packing may be applied between collar B andthe flange of the tube K, also in the tube K, for the end of the tube Dto screw against and on the tube D for the end of the tube K to screwagainst, if desirable.

The tube A, of this coupling can be readily applied and connected to thetube D, in the dark even while the engine is in operation, and thewat-er flowing through the hose, as it can be pushed together and lockedso quick; and after it is locked the tube A, holds the tube K, straightand square with the tube D, so that the tube K, can be pushed up to theend of D, and turned, and as it is held in a proper position by the tubeA, the screw is sure to catch readily, so that it may be turned up andmake the connection sure, so that the hose may be turned to take out thetwist without any risk of separating the coupling.

lVhile the old fashioned screw coupling requires such careful andprecise adjustment to make the screws catch; that it is very I will novvstate what I desire to secure diflicult and almost impossible to connectby Letters Patent to Wit:

them in the dark, and entirely out of the I claim- 15 question toconnect them When the engine The'locking devices described in combi- 5is Working and the Water flowing through nation With the screw tube K,arranged in the hose; hence the advantage of my imconnection With and onthe outside of said provement in connecting the lock coupling lockingdevices substantially as described. With the screw, as heretoforedescribed.

I believe I have described and represented A' HENRY LOWELL' l0 myimprovements in hose couplings, so as Witnesses: 4
